Hector "Tank" Martinez popped the question to his girlfriend Paige Hernandez last Sunday during a "Unity Ride," an event where solo and club bikers ride together.

Hundreds of motorcycles held back 5 lanes of traffic, while others provided a smoke screen for the dangerous proposal.

Martinez said his girlfriend wanted him to propose on the bike scene with their family present.  "By proposing on the freeway and having all of our family members on the overpass watching, ” he said he was able to “give her the best of both worlds."
